されていく。As described above, according to the present invention, during an open inspection of a low-temperature liquefied gas tank, a portion of the boil-off gas to be discharged into the boil-off gas line for residual liquid after discharging is heated and pressurized to be induced into the bottom of the tank, and the remaining liquid is removed. In order to use a method in which the gas is spouted into the liquid liquefied gas, the above-mentioned spout temperature increase is achieved even though a certain amount of low-temperature liquefied gas inevitably remains when discharging the stored low-temperature liquefied gas due to the limitations of the tank structure. The return boil-off gas performs gas-liquid contact, aeration, and agitation, so that the stored residual low-temperature liquefied gas is rapidly boiled off and quickly discharged from the tank to the outside of the system.

検査能率が向上するという優れた効果が奏される。Therefore, forced boil-off of the low-temperature liquefied gas remaining at the bottom of the tank is performed much faster than natural boil-off, and the time from the start of discharging the stored low-temperature liquefied gas to the start of tank opening inspection is correspondingly shorter. shortened,
The excellent effect of improving inspection efficiency is achieved.
